Aerial stems dimorphic; vegetative stems green, branched, 30–100(–200) cm; hollow center 2/3–3/4 stem diam. Sheaths squarish in face view, 7–18 × 5–13 mm; teeth green proximally and dark distally, 14–30(–36), 3–12 mm. Branches in regular whorls, ascending to spreading, solid; ridges 4–5, furrowed; valleys rounded; 1st internode of each branch shorter than subtending stem sheath; sheath teeth attenuate. Fertile stems brown, lacking stomates, unbranched, shorter (17–45 cm) than vegetative stems, with larger (15–40 mm) sheaths, fleshy, ephemeral.
Phenology: Cones maturing in early spring.
Habitat: Coastal marshes, stream banks, ditches, and other wet places
Elevation: 0–1000 m
Distribution
